NON-REFILLABLE BOTTLE.

Speccation of Letters Patent.

Patented Dec. 8, 1914.

Application iled September 23, 1912, Serial No. 721,826. Renewed April 29, 1914. Serial No. 835,337.

To all 'whom it may concern:

Be it known that we, FREDERICK NICHOLS BowNn and DANIEL I. Hawkins, citizens of the United States, residing at Corona, borough of Queens, in the county of Queens, city and State of New York, have invented certain new and useful Improvements in Non-Refillable Bottles, of which the following is a specification, reference being had therein to the accompanying drawing.

Our invention relates to a means for preventing the refilling of bottles.

Objects of the invention are to provide an improved means for the indicated purpose, of simple and practical form, and involving a minimum cost of manufacture, and to provide a novel device to lock the parts in the bottle neck.

The distinguishing features of our invention, and the important structural elements characterizing the ypreferred embodiment which is illustrated 'as an example, will be more particularly explained in the specic description hereinafter to be given.

Reference is to be had to the accompanying drawings forming a part of this specication, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a vertical section showing our invention applied to a bottle neck; Fig. 2 is a similar view showing the position the parts assume when the bottle is inverted; Fig. 3 is a cross section on the lines 3-3 of Fig. 1; and Fig. 4 is a cross section on the line 4 4 of Fig. 1.

In constructing the practical embodiment illustrated as an example of our invention, the bottle 10 may be of any approved design, having the neck 11 within which is fitted a shell 12, preferably of glass, the neck and shell being formed with mating annular recesses 13, 14, which receive a resilient locking device 15 in the form of a semi-circular metallic element having its ends 16 return-bent, the arrangement being such that when the shell is inserted in the neck, with the lockingdevice 15 in the groove 14, the said element, when the recess 13 is reached, will spring outward, thus securely fastening the shell in place. Packing rings 17, of cork or other approved material, are fitted on the shell 12 outside of the locking device 15, and an additional packing ring 18 may be employed at the inner end of the shell and fitting between the shell and the base ofthe neck 10.

A baffle partition 19 is yformed in theshell 12 and extends transversely of the bottle neck, and below the partition at diametrically opposite points, outlet openings 2O are formed in the shell, there being corresponding inlet openings 21 above the partitions adjacent to the outlets 20. As best shown in Figs. 2 and 3, diametrically opposite side edges of the partition 19 lterminate short of the peripheral surface of the shell 12, thereby producing a vertical passage 19 between each outlet 20 and the adjacent inlet 21, said passages being of arcuate shape transversely, as in F ig. 3, and affording ample space for the flow of liquid between the partitions and the inner surface of the bottle neck 10.

Fitting within the inner end of the shell 12 is a bushing 22, having a reduced diameter near the inner end, presenting an internal shoulder 23, forming a valve seat, and the upper end 24 of the bushing terminates a distance below the partition 19 and constitutes another valve seat on which a buoyant valve 25 is adapted to seat, said valve being permitted play between its` valve seat and the partition 19. A second valve 26, desirably formed of glass, is provided below the valve 25, and adapted to rest on the seat 23.

A pendulous weight 27 is suspended from the valve 26, and connected therewith by an articulated valve stem, the stein preferably being formed by molding into the glass weight 27 a rod 2S, and molding a similar rod 29 in the valve 26, the two rods being formed with eyes 30, 31, that interengage each other. The bushing 22 has a peripheral flange 23a at its end, which bears against the inner end of the shell 12, and the inner packing ring 1S extends continuously around said flange and around the adjacent portion of the shell 12, closing the joint between the two.

In practice, the inner valve 26 will be maintained on its seat by the weight 27, even should the bottle be tilted to about the horizontal position, but the pressure of the liquid when the bottle is tilted will be sufficient to move the valve from its seat and permit an outflow of the liquid. Should it be attempted to refill the bottle when inverted, or partially so, the buoyant valve 25 will be floated against its seat 24, thus closing the bottlek against the entrance of an incoming liquid. The outflow through the passages 19a is sufficient for the purpose, while the formation of the devices at this point aords an effective baffle to the entrance of any device should an attempt be made to tamper with the valves.

Except for the locking device 15, the valve stem, the buoyant valve and the packf ing rings, the various parts may be formed from glass, and the assembled parts may be inserted in the bottle neck 10. Surrounding the shell l2, near the outer end and above the bottle neck 10, a ring` or collar' 32 Vmay be provided, to give a inish and to form a closure for the space between the bottle neck and shell.

It will be seen that the inner neck is in a single piece, the transverse guard partition being integral, the upper end beyond the guard partition receiving the stopper, and the said neck extending belov7 the partition in plain cylindrical form to the lower end so as to receive the bushing 2Q to be slipped into the shell from the inner end. There is no special form of valve seat required, the substantially plain cylindrical form of the upper end presenting an edge which, by its mere contraction of the interior of the shell, forms a valve chamber and valve seat, while the contraction of the diameter of the bushing forms a second lower valve seat. A shell therefore of simple form and a correspondingly simple bushing locate and retain the valves, the outer iiange at the inner end of the bushing determining the position of the Copies of this patent may be obtained for upper valve seat andv limiting the inward I movement of the bushing.

Having thus described our invention, We claim as new, and desire to secure by Letters Patent:

In a bottle closure, the combination with the bottle neck, of a cylindrical shell fitting. within said neck, the said shell having an integral transverse guard partition below the top thereof, and outlets around said partition, the shell below the partition extend; ing in plain cylindrical form to its lower end to receive a bushing, a cylindrical bush-v ing fitting the shell at the inner endV and formed with an exterior lateral flange abutting against the innerend of the shell, the said bushing being of reduced diameterat its lower end presenting an internal shoulder between the upper and lower ends, the said shoulder constituting a valve seat, and the bushing extending in cylindrical form from the said shoulder to the upper end, the extreme upper edge ofv the cylindrical upper end being disposed below the guard partition of the shell and constituting a second valve seat, and valves seating on the said valve seats.

In testimony whereof we hereunto affix our signatures in the presence of two witnesses'. l
